Bug ID: 109920
Summary: "NIR validation failed in internal shader" abort with
all Vulkan test-cases
Product: Mesa
Version: git
Hardware: x86-64 (AMD64)
OS: All
Status: NEW
Severity: critical
Priority: medium
Component: Drivers/Vulkan/radeon
Assignee: mesa-dev@lists.freedesktop.org
Reporter: eero.t.tammi...@intel.com
QA Contact: mesa-dev@lists.freedesktop.org
Setup:
* KBL 8809G (HadesCanyon)
* Ubuntu 18.04
* drm-tip kernel, X server and Mesa built from Git
* Any Vulkan test
Test-case:
* Run Sacha Willems' Vulkan triangle test
./triangle
Expected outcome:
* Vulkan tests work with RADV, like they do with ANV
* Actual outcome:
---------------------------------
$ ./triangle

---------------------------------
This has regressed within past day, between:
2019-03-04 17:33:17 610758d3e54027: egl/sl: also allow virtgpu to fallback to
kms_swrast
2019-03-05 16:06:50 43f40dc7cb234e: anv: Implement VK_EXT_inline_uniform_block
And it's still broken with Git tip.
